The sheet-shaped photographic paper 1 is formed by a pair of squeeze rollers.
And squeeze the upstream squeeze roller 2
1 and 22 and a pair of downstream squeeze rollers 23 and 24. Thus, since there are only two squeeze roller pairs in the squeeze unit 20, the structure is such that the drying unit 8 of the automatic developing machine can be made small and inexpensive.

The upstream squeeze rollers 21, 2
2 and the pair of the downstream squeeze rollers 23 and 24 are horizontally arranged, and the liquid squeezed by the pair of the upstream squeeze rollers 21 and 22 is used for the downstream squeeze rollers 23 and 2.
Since the sheet 4 does not hang down, the sheet-shaped photographic paper 1 can be dried at a higher speed.

The transport roller group 30 has a pair of inlet transport rollers 31, 32 and a pair of outlet transport rollers 33, 34. Then, the sheet-shaped photographic paper 1 is transported by the pair of the entrance transport rollers 31 and 32 and the pair of the exit transport rollers 33 and 34. Further, grooves 35 and 36 are provided in the pair of the entrance conveyance rollers 31 and 32 and the pair of the exit conveyance rollers 33 and 34, respectively, in the width direction.

Then, these rollers rotate the sheet-like photographic paper 1 at the transport speed VP.
In order to transport the gears, the common drive motor 41 rotates the drive gear 43 provided on the motor shaft 42 from the gear 4.
The pair of upstream squeeze rollers 21 and 22 are driven to rotate via the gears 4 and 45, the pair of downstream squeeze rollers 23 and 24 are driven to rotate via the gears 46 and 47, and the gears 48, 49 and 50 are further driven. Through the entrance conveying rollers 31 and 32

The outlet conveying rollers 33 and 34 are rotationally driven via the rollers 4 and 55.

Further, the hot air blower 10 is an inexpensive one obtained by diverting a hair dryer whose outlet 11 is narrowed. Then, while guiding the sheet-shaped photographic paper 1 from the squeeze unit 20 to the entrance conveyance rollers 31 and 32, the hot air blower 1

The sheet-shaped photographic paper 1 can be dried and heated to a high temperature while efficiently blowing off the water vapor around the paper 1. The length of the air outlet 11 in the conveying width direction is 1/1 / the width of the photographic paper 1 on the sheet.
This is about 1/3 of 2 or less, but instead, an effective flow of hot air is generated, and more rapid drying can be performed.

Since the sheet-like photographic paper 1 is conveyed in the automatic developing machine at a predetermined conveying speed VP, the sheet-like photographic paper 1 passes through the detector 3 provided on the upstream side of the processing section 7 in the conveying direction. , The hot air blower 10 starts sending hot air after a predetermined time TR. Assuming that the transport distance LP is from the detector 3 to the slit hole entrance 25 of the squeezing unit 20 of the drying unit 8, the sheet-shaped photographic paper 1 is sent to the slit hole entrance 25 of the squeezing unit 20 of the drying unit 20. The hot air blower 10 starts sending hot air before a predetermined time TW shown by the equation.

TW = LP / VP-TR This ensures that the hot air blower 10 starts sending hot air before a predetermined time TW before the sheet-shaped photographic paper 1 is sent to the drying unit 8, so that the downstream side squeezing is performed. Rollers 23, 24
Can be heated to a higher temperature, so that sheet-like photographic paper 1
Can be dried.

Further, the temperature adjustment of the color developing solution in the color developing step 4 of the processing section 7 and the hot air blower 10 (including both the heat source and the blower) are performed by electric power from a common power supply. By alternately using the power of the common power supply, the power consumption is kept within the rated power of the common power supply. In this case, the power of the common power supply is used alternately so that the power consumption is kept within the rated power of the common power supply. The time TP from the detection to the time when the sheet-shaped photographic paper 1 passes through the color development processing step 4 is equal to or longer than TP. That is, the predetermined time TW is a time represented by the following equation.

TW <LP / VP-TP The entrance of the squeezing section 20 of the drying section 8 is blocked except for a slit hole entrance 25 for passing the sheet-like photographic paper 1. As a result, the temperature of the stabilization processing liquid in the stabilization processing step 6, which is the last processing step of the processing unit 7, is high, so that the hot air from the hot air blower 10 flows to the stabilization processing step 6 and the stabilization processing is performed. Evaporating the stabilizing solution in Step 6 to prevent the stabilizing solution from being deposited.
